Model CrossHX represent the model of a cross flow plate
heat exchanger where air is used as secondary fluid. Pressure drop
is taken into account in the air side. It is based on the
connection of different sub-components:
- A Flow1Dim component representing the flow of the fluid in one
side of the exchanger
- A MultiFlow1D component representing the flow of air in the
other side of the exchanger
- A MetalWall component representing the thermal energy
accumulation in the metal wall
Modelling options
In the Initialization tab the following options are
availabe:
- steadystate_wf: if true, the derivative of enthalpy of the
working fluid is set to zero during Initialization
- steadystate_T_wall: if true, the derivative of temperature of
the metal wall is set to zero during Initialization
- constinit_sf: if true, the pressure drop in the air side is set
to a constant value during Initialization
- UseHomotopy_sf: if true, it uses homotopy to set the pressure
drop to zero during Initialization
Numerical options
The numerical options available for the CrossHX are the
one implemented in Cell1Dim.
